Location of the Wear, Interdisciplinary Workflow and Therapeutic Approach for Tooth Wear: LIT Classification.

Area of Science:

• Dentistry
• Restorative Dentistry
• Dental Biomaterials

Background:

• Tooth wear (TW) is a progressive, non-carious loss of dental structure from erosion, attrition, and abrasion, often affecting young patients.
• Its multifactorial nature and association with other oral conditions necessitate complex, interdisciplinary management.
• Current classifications lack integration of wear extent, location, and involved specialties for comprehensive treatment planning.

Purpose of the Study:

• To present a structured, minimally invasive guide for dental wear rehabilitation.
• To introduce the LIT (Lesion-to-Intervention-Type) classification system for guiding restoration choices.
• To enhance predictability, communication, and biological preservation in managing worn dentition.

Main Methods:

• Development of a structured treatment sequence based on wear location, extent, involved disciplines, and therapeutic approach.
• Introduction and application of the LIT classification to correlate lesion magnitude with restoration type and material selection.
• Emphasis on interdisciplinary planning and a personalized approach to treatment.

Main Results:

• The LIT classification effectively links tooth wear magnitude to appropriate restoration type and extension.
• A structured, minimally invasive approach improves diagnosis, communication, and treatment predictability.
• The proposed system facilitates conservative and efficient oral rehabilitation.

Conclusions:

• Rehabilitating worn dentition demands precision, interdisciplinary planning, and a focus on tooth preservation.
• The LIT classification enhances diagnosis, communication, and predictability by guiding restoration choices based on wear severity.
• Minimal invasion, appropriate material selection, and personalized patient care are crucial for long-term functional and esthetic success.
